Adobe Reader X (10.1.0) with msp

I am having an issue creating/deploying a package for Adobe Reader X (10.1.0). I have created my Transforms file, placed all necessary files into 1 folder, and zipped. This package has then been uploaded to KBOX 1000.

However when I attempt to install I get a Windows Installer Error, advising the package could not be opened.

My Command Syntax to install is as follows:

msiexec.exe /qn /i "acroread.msi" TRANSFORMS=file.mst.

I pulled this command directly from our Adobe 10.0.1 installation, and verfied that it works. I am at a loss then, as to why it will not work for the new package.

NOTE: I have gone into the download folder on the local PC (where KBOX stores the files) and double clicked on the newly downloaded acroread.msi...which opens fine.....needless to say I am very confused.
